MIPI VGI Verification IP
General-purpose I/O states carried as messages over a serial link instead of dedicated pins.
MIPI VGI verification IP
MIPI Virtual GPIO Interface replaces many sideband GPIO wires with messages over a serial link.
Lumina VIP for MIPI VGI covers Virtual GPIO, as published by MIPI Alliance. It comes as verification IP, built for Lumina, so the same components run in simulation and report their results in one place.
What the MIPI VGI VIP covers.
Protocol
- GPIO state messages and virtual pins
- Message timing and ordering
Checks and error injection
- Mapping of physical GPIOs to virtual pins
- Latency of state changes across the link
- Message loss and retry
Scenarios and options
- Bursts of simultaneous pin changes
What it checks
- Packet structure, ECC and CRC
- PHY states, lane control and timing
- Virtual channels, data types and commands
- Low-power entry and exit
Verification IP capabilities
- Active and passive agents for every protocol role, set per instance
- Bus widths, timing and optional features set by parameters, and changeable while a test runs
- A sequence library from basic directed traffic to constrained-random stress
- Error injection, static or on the fly, with checks that the expected error was seen
- Protocol checks that run in real time, each tied to a rule of the specification
- Scoreboards that check data end to end
- Throughput, latency and utilisation statistics for each interface
- Callbacks at each stage for your own checks and stimulus
- UVM register model adapters for protocols that carry register access
- Transaction logs and messages linked to the waveform for debug
Why Lumina VIP.
- Fast MIPI VGI testbench bring-up: connect the agents, pick a test and run
- Every failure names the rule it broke and the transaction that broke it
- Protocol coverage merges with your design coverage in one database
- Readable SystemVerilog and UVM source your team can extend
- Runs natively in Lumina Sim, with no wrappers and no separate compile
- Results structured for engineers and AI agents alike
Verification components.
Each component works on its own or together with the others in one environment, in active or passive mode.

Frequently asked questions.
What is Lumina VIP for MIPI VGI?
Lumina VIP for MIPI VGI is a set of verification products for designs that use MIPI VGI: verification IP. General-purpose I/O states carried as messages over a serial link instead of dedicated pins.
Which MIPI VGI versions does it support?
Virtual GPIO, as published by MIPI Alliance. If you need another version or option, tell us which one.
Which verification components are included?
Transmitter, Receiver and Passive monitor. Each one can be used on its own or together with the others in one environment.
What language and methodology does it use?
The verification IP and models are written in SystemVerilog with UVM, as readable source your team can extend.
How does it work with Lumina?
It runs in Lumina Sim beside your RTL. Protocol coverage merges into the same database as your own coverage, and every violation names the rule it broke and the transaction that broke it.
Which tests come with it?
Directed tests for each feature of the specification. Constrained-random tests across configurations and traffic mixes. Error-injection tests that check how the design recovers. A functional coverage model mapped to the specification. Regression lists ready to run in Lumina. For this protocol family the tests focus on: every lane count and data rate in scope, low-power and high-speed transitions, each packet and data type and header, CRC and protocol errors.
What is delivered?
Readable source of every component. The test suite and its coverage model. An example environment connected to a sample design. User guide, integration guide and release notes. Scripts to run the examples in Lumina.
